Cmplx rpr trunk 2.6-7.5 cm
CPT 13101 covers complex repair of wounds on the trunk (chest, back, abdomen) measuring 2.6 to 7.5 centimeters that require layered closure involving deeper tissues beyond simple skin stitching.
This calculator gives a typical-case estimate using standard Medicare modifier rules. Actual payment depends on payer policies, documentation, code-specific CMS status indicators, and locality. Verify before billing.

Billing tips
Measure and document exact wound length before debridement or preparation - use the final repaired length, not the original traumatic wound if extended surgically
Impact: Incorrect measurement can result in downcoding to 13100 (≤2.5 cm) with payment reduction of approximately $126 per case
Clearly document all layers closed (dermis, subcutaneous tissue, fascia) with specific suture materials and techniques used for each layer
Impact: Lack of layered closure documentation results in downcoding to intermediate repair (12032-12037) with reimbursement loss of $200-250
Bill in non-facility setting when performed in office to capture the $381.37 rate versus $239.36 facility rate
Impact: Setting optimization yields $142.01 additional revenue per procedure (37% increase)
For wounds 7.6 cm or larger, use add-on code 13102 for each additional 5 cm or less beyond initial 7.5 cm
Impact: Failing to bill 13102 for qualifying wounds results in $150-200 lost revenue per additional segment
When multiple trunk wounds are repaired, sum the lengths of wounds in same classification and same anatomic grouping rather than billing separately
Impact: Per CPT guidelines, this may result in billing one larger repair code with higher reimbursement than multiple smaller codes subject to multiple procedure reductions
Do not separately bill simple debridement or local anesthesia - these are included in the repair code
Impact: Unbundling these services triggers audits and recoupment; extensive debridement requiring significant time may qualify for separate 11042-11047 codes
